Call or other emergency services right away if:

  • You have signs of severe dehydration. These include little or no urine; sunken eyes, no tears, and a dry mouth and tongue; fast breathing and heartbeat; feeling very dizzy or lightheaded; and not feeling or acting alert.
  • You think you may have food poisoning from a canned food and you have symptoms of botulism (blurred or double vision, trouble swallowing or breathing, and muscle weakness).

Talk to your doctor if:

  • You have symptoms of mild dehydration (dry mouth, dark urine, not much urine) that get worse even with home treatment.
  • You have a fever.
  • You aren't feeling better after 1 week of home treatment.

If you think you have eaten contaminated food, your local Poison Control Center can answer questions and provide information on what to do next. Poison Control Centers are usually listed with other emergency numbers in your telephone book.

Children, pregnant women, and people with long-lasting (chronic) conditions, such as diabetes, are more likely to have severe dehydration and should be watched closely for symptoms.

Watchful waiting

Watchful waiting is a period of time during which you and your doctor observe your symptoms or condition without using medical treatment.

Watchful waiting may be appropriate if you have diarrhea, stomachcramps, and other symptoms of stomach flu (gastroenteritis). Most people recover from these gastrointestinal illnesses at home in several days without medical treatment. Likewise, some cases of bacterial food poisoning are mild and pass in several days. But if diarrhea is severe or lasts longer than a week, call your doctor for advice.

Who to see

Health professionals who are able to diagnose and treat food poisoning include:

You may be referred to a gastroenterologist if your symptoms are persistent or severe.
